However, the system then issued a strange instruction: lurk and observe Lin Wan'er for a week and collect all her privacy! Is she an innocent white-collar worker, or a key pawn of the terrorist organization "Ivy League Plan"? On one side is the gentle smile of the savior, on the other is the cold threat of erasure from the system. How do little people survive in the big chess game? When the biological weapons crisis approached, Xia Zhitong could only carry an invisible voice recorder and frantically test the gap between lies and truth.
